Application filed January 16, 1931. Serial n. 505,2 2.

This invention relates to an appliance or structure which may be conveniently referred to in the following specification and claim as an automatic waterfeeder and it has more particular reference to an especially designed contrivance developed to control the supply of water to a humidifier of the type used in association with present-day hot air furnaces.

These humidifiers are of diversified construction according to the particular kinds of furnaces with which they are used. Generically considered however, the humidifier details, all of which are embodied in a novel cover for the tank.

'In carrying the inventive conception into practice, I have evolved and produced a feasible arrangement of details characterized by a cover for-the humidifier tank wherein will vary in shape, size and proportions ac- Moreover, I have merelydisclosed an especially formed casting which constitutes the cover for the tank and which in practice will vary m in shape and proportion. The general principle of-construction is the sameirrespective of the particular tank and cover.

In the drawings:

Thispart 13,; includes a tubular'body portion 14- projecting '75 into the connection 11 and having its upper end provided witha strainer or screen 15'. The lower end portion thereof is provided withiaflange carrying a packing ring l6 to provide a watertight connection. "The central bore' of this fitting is shaped intermediate its ends to provide a valve seat "with which the head 16 ofthe valveelement 17' isngageable.- The stem of the valveiis' carried by'a rocker 18? whichis pivotedas at'19 be- 85' tween a pair ofdependin'g lugsQO onf'tlie undersideofthe ooverl, i

The stem is also provided with an annular gasket or ring'21 which directly'co-operates V with theivalve seat. The rocker isswingably mounted at a point'intermediate it's-ends and one end portion 21 fits telescopically into'a t11bular-rodor pipe 22which in turn extends into socket 23 formed in the float 24. It

When the water at theproper level. the

float closes the valve. When the water recedes to an abnormal low level, the float drops I0 ,to facilitateassembly and constitutes aeunit with the'rockenvalve element, seat and pack ing means as is evidentfrom Figure v It is thought that the description, taken in connection with the drawings willlena'ble I I a a clear understanding of the: invention to be r V Y had, 7 Therefore, a more lengthy description and opens the valve to permit replenishment of the tank. The dimensions and proportions of-parts are such as to permit this auto i matic opening and closing of the valved sup- 1 ply line at predetermined intervals of time.

' The principal details of the structure are as follows. .The cover 8 is of suitable shape,

size and proportions, and by preference in I eludes an integral dome-like hollow connec- .tion or extension 11 which is elevated and provided with a nipple to accommodate-the 1 watersupply pipe (not shown).

On its underside and located "beneath'this extension 11 are hanger ears or lugs 20 which.

serve to suspend the balanced rocker, said rocker being provided on one end with a valve elementand on the other end with a tubular I arm22 carrying the remote float. The espe- I cially designed packed fitting which projects into thepart 1 1 is important. I'Itissuch' as is thought unnecessary;

. While theprefrred'enibodiment ofthein' vention has been shownand described, it is to begunderstood that minor changes in shape, v s ze, and rearrangement ofvdetails coming. p within the field of invention claimed may be a a Lresoi'ted to in-actual; practice if desired with out departing from the spirit and scope 1 of the appendedc'laimlI cla-imr .1 i y.

the dome with an enlarged part extending from the lowerrface of the cover, a gasket located between the said enlarged partend the under face of the coverfor forming a liquid tight; joint between the plug and the dome, a screen in the upperpart of the plug, a valve seat formed in the plug, avalve'having a stern V-p'rojecting: fronrthe plug, a gasket on the ,valve -having rangenlarged upper part V forming a seat with the'lower part for engagr ing the-valve seat, earsdepending from the 7 cover, a rocker arm pivoted between theears having one end engaging the. lower end of the valve,-a tube fitting over the other end of the rocker, arm, anda tank forming a float i connected to the opposite end-ofthe' tube.-
